# EvalPlus 代码评测 自包含脚本 (HumanEval+ / MBPP+, vLLM 后端, greedy pass@1)
# 由 code_eval/run_evalplus.sh 抽取, 路径改为本目录相对, 可独立搬运。
# 官方项目: https://github.com/evalplus/evalplus (已装在集群 vllm conda 环境)
#
# 数据: ./data/ (HumanEvalPlus-v0.1.10.jsonl, MbppPlus-v0.2.0.jsonl);
#       运行时若 ~/.cache/evalplus 缺数据, 自动从 ./data 离线补齐 (不联网也能跑)
#
# 用法:
#   sbatch --export=ALL,MODEL=/data/icto/mc56499/model/Qwen2.5-Coder-3B \
#       /data/icto/mc56499/eval/code/run_evalplus.sh          # pro6000 2卡
#   sbatch --export=ALL,MODEL=... -p gpu-l40s run_evalplus.sh # 换分区
#   bash run_evalplus.sh [/模型路径] [TP]                      # srun/交互调试
#
# 产物: <本目录>/evalplus_results/
#   samples: evalplus_results/<dataset>/<model>_vllm_temp_0.0.jsonl
#   报告:    同目录 *_eval_results.json (含 pass@1 base/plus)
